[0] Seed Value
[1] Segment ID
Default: 1
MethodChoiceDOWNChoose if you want to segmentate either on minima or on maxima.Available Choices:
[0] Minima
[1] Maxima
Default: 1
Join Segments based on Threshold ValueChoiceJOINJoin segments based on threshold value.Available Choices:
[0] do not join
[1] seed to saddle difference
[2] seeds difference
Default: 0
ThresholdFloating pointTHRESHOLDSpecify a threshold value as minimum difference between neighboured segments.Minimum: 0.000000
Default: 0.000000
Allow Edge Pixels to be SeedsBooleanEDGE-Default: 1
BordersBooleanBBORDERSCreate borders between segments as new grid.Default: 0
